Question

Mark the correct alternative in the folowing question:

$$\begin{gathered} {\left(-\frac{3}{5}\right)}^{-1}= \\ \left(\mathrm{a}\right)\frac{3}{5}\left(\mathrm{b}\right)\frac{5}{3}\left(\mathrm{c}\right)-\frac{5}{3}\left(\mathrm{d}\right)-\frac{3}{5} \end{gathered}$$

Answer 1

Since, ${\left(-\frac{3}{5}\right)}^{-1}=-\frac{5}{3}\left(\mathrm{As},x^{-1}=\frac{1}{x}\right)$

Hence, the correct alternative is option (c).
